Here's an excerpt from the article:
In WPF/Silverlight ScrollViewer and ScrollBar control doesn't have any property to change color of Thumb dynamically from XAML by setting property. We have to edit the Style of ScrollBar and set the Brush for it according to our requirement. Based on requirement of one of the user on MSDN Forum I decided to create a Custom ScrollViewer which has a property to set Brush for Thumb.
SharedSub New ``()
DefaultStyleKeyProperty.OverrideMetadata(``GetType`` (CustomScrollViewer), ``New FrameworkPropertyMetadata( ``GetType``(CustomScrollViewer)))
PublicProperty ScrollBarThumbBrush ``AsBrush
Set``(``ByVal value ``AsBrush)
PublicShared ReadOnly ScrollBarThumbBrushProperty ``AsDependencyProperty = DependencyProperty.Register(``"ScrollBarThumbBrush"`` , ``GetType`` (Brush), ``GetType`` (CustomScrollBar), ``New PropertyMetadata(Brushes.Gray))
